GETSOCKNAME

NAME

SYNOPSIS

DESCRIPTION

Getsockname
returns the current
name
for the specified socket. The
namelen
parameter should be initialized to indicate
the amount of space pointed to by
name.
On return it contains the actual size of the name
returned (in bytes).

RETURN VALUE

On success, zero is returned. On error, -1 is returned, and
errno
is set appropriately.

ERRORS

EBADF

The argument
s
is not a valid descriptor.

ENOTSOCK

The argument
s
is a file, not a socket.

ENOBUFS

Insufficient resources were available in the system
to perform the operation.

EFAULT

The
name
parameter points to memory not in a valid part of the
process address space.

CONFORMING TO

NOTE

The third argument of
getsockname
is in reality an `int *' (and this is what BSD 4.* and libc4 and libc5 have).
Some POSIX confusion resulted in the present socklen_t.
The draft standard has not been adopted yet, but glibc2 already
follows it and also has socklen_t. See also
accept(2).
